JavaScript to enable "submit" button (doesn't work)

- by Halst

I need the button "submit" to be disabled unless JavaScript is on. I tried: 1. <input onLoad="this.disabled=false" id="post-comment" type="submit" value="Post Your Comment" disabled="disabled"/> 2. <input onLoad="this.removeAttribute("disabled");" id="post-comment" type="submit" value="Post Your Comment" disabled="disabled"/> 3. <input onLoad="document.getElementById("post-comment").removeAttribute("disabled");" id="post-comment" type="submit" value="Post Your Comment" disabled="disabled"/> Doesn't work. I'm new to JavaScript, but can't find answer on the net.

Updating cached counts in MySQL

- by phleet

In order to fix a bug, I have to iterate over all the rows in a table, updating a cached count of children to what its real value should be. The structure of the things in the table form a tree. In rails, the following does what I want: Thing.all.each do |th| Thing.connection.update( " UPDATE #{Thing.quoted_table_name} SET children_count = #{th.children.count} WHERE id = #{th.id} " ) end Is there any way of doing this in a single MySQL query? Alternatively, is there any way of doing this in multiple queries, but in pure MySQL? I want something like UPDATE table_name SET children_count = ( SELECT COUNT(*) FROM table_name AS tbl WHERE tbl.parent_id = table_name.id ) except the above doesn't work (I understand why it doesn't).

SQL: Optimize insensive SELECTs on DateTime fields

- by Fedyashev Nikita

I have an application for scheduling certain events. And all these events must be reviewed after each scheduled time. So basically we have 3 tables: items(id, name) scheduled_items(id, item_id, execute_at - datetime) - item_id column has an index option. reviewed_items(id, item_id, created_at - datetime) - item_id column has an index option. So core function of the application is "give me any items(which are not yet reviewed) for the actual moment". How can I optimize this solution for speed(because it is very core business feature and not micro optimization)? I suppose that adding index to the datetime fields doesn't make any sense because the cardinality or uniqueness on that fields are very high and index won't give any(?) speed-up. Is it correct? What would you recommend? Should I try no-SQL? -- mysql -V 5.075 I use caching where it makes sence.

How to create wordpress-like option table and get values for each row? (PHP-MySQL)

- by Nacho

Hi guys. I'm looking to create an options table in my db that makes every record a system option, so i can work with a little number of fields. my db has the following structure: 3 columns named id, name, and value following data is inserted as an example -- id - name - value 1 - uri - www.example.com 2 - sitename - Working it out 3 - base_folder - /folder1/folder2/ 4 - slogan - Just a slogan for the site -- that way i can include a large number of customizable system options very easily the problem is that i don't know how to retrieve them how do i get the value of uri and store it as a var? and better yet, how do i get, for exmaple, values of id 1 and 4 only without making a query each time? (i assume multiple queries are useless and a pretty ugly method) i know the question is pretty basic but i'm lost here. i'd really appreciate your answer! Thanks in advance

jquery add remove objects

- by Scarface

Hey guys quick question, I have an add remove script that will add a unique element and should remove it on a click function but does not. I think it is because the added object is not in the DOM when page is loaded but I am not sure how to fix this. IF anyone has any advice I would greatly appreciate it. $(document).ready(function(){ if (action=='content-change'){ $('#droppable2-inner').empty().append('<div id="content-image"><img id="visual-background2" src=' + src + '></div><div id="drop-content" action="drop-image">x</div>'); } $("#drop-content").click(function() { $('#content-image').remove(); }); })

Updating multiple rows with an array

- by Copephobia

I have a table that holds user information. One of the columns holds the position of the user in the game they are in. When a game is being created, I need to update the positions of the users of each team. Here is an example: Game id : 7 Team 1 users : 1,2 Team 2 users : 3,4 team1_position : array(1,2) team2_position : array(13,14) What I want to do is update the user table using the array of positions in the SET area. My goal is to be able to update the users without the need for their id (I have different size game boards, so I have multiple position arrays for each board size) How can I do something like this: UPDATE user SET position='(team1_position)' WHERE game = '7' AND team = '1' I feel like it would be a waste of resources to select all the id's of each team and update them separately.

Review of a locked part of an function in C#.NET

- by Lieven Cardoen

Is this piece of code where I lock a part of the function correct? Or can it have use drawbacks when multiple sessions ask concurrently for the same Exam? Purpose is that client that first asks for the Exam will assemble it, all next clients will get the cached version. public Exam GetExamByExamDto(ExamDTO examDto, int languageId) { Log.Warn("GetExamByExamDto"); lock (LockString) { if (!ContainsExam(examDto.id, languageId)) { Log.Warn("Assembling ExamDto"); var examAssembler = new ExamAssembler(); var exam = examAssembler.createExam(examDto); if (AddToCache(exam)) { _examDictionary.Add(examDto.id + "_" + languageId, exam); } Log.Warn("Returning non cached ExamDto"); return exam; } } Log.Warn("Returning cached ExamDto"); return _examDictionary[examDto.id + "_" + languageId]; } I have a feeling that this isn't the way to do it.

How to get a List ordered by the List it's filtered by?

- by DaveDev

I have a method as follows. It returns a list of MyTypes which appear to be ordered by myType.Id ascending by default. public List<MyType> GetMyTypes(List<int> ids) { return (from myType in db.MyTypes where ids.Contains(myType.Id) select new MyType { MyValue = myType.MyValue }).ToList(); } So if ids contains 302 300 301 the List returned contains items in ascending order. What do I need to do to return List<MyType> in the order of ids? Thanks edit: I've tried orderby ids.IndexOf(myType.Id) but it throws the exception Method 'Int32 IndexOf(Int32)' has no supported translation to SQL.

Very simple mod_rewrite questions

- by Camran

1- Does mod_rewrite means that if I make this url: domain.com/ad.php?id=8498292 INTO domain.com/8498292 that all links on my website will have to be changed to the later above? example the link: domain.com/ad.php?id=8498292 wont work now, unless I replace it with domain.com/8498292 ? Or will the server know that they are the same still? 2- Will the rewritten link appear rewritten in the browsers adress bars also, so if I enter domain.com/ad.php?id=8498292 it will actually appear as domain.com/8498292 in the adress bar itself? 3- Will images and all other related links and material on the page whose link is rewritten remain intact? ie will pictures and links still work FROM that page which are relative? Thanks

Strange Locking Behaviour in SQL Server 2005

- by SQL Learner

Can anyone please tell me why does the following statement inside a given stored procedure returns repeated results even with locks on the rows used by the first SELECT statement? BEGIN TRANSACTION DECLARE @Temp TABLE ( ID INT ) INSERT INTO @Temp SELECT ID FROM SomeTable WITH (ROWLOCK, UPDLOCK, READPAST) WHERE SomeValue <= 10 INSERT INTO @Temp SELECT ID FROM SomeTable WITH (ROWLOCK, UPDLOCK, READPAST) WHERE SomeValue >= 5 SELECT * FROM @Temp COMMIT TRANSACTION Any values in SomeTable for which SomeValue is between 5 and 10 will be returned twice, even though they were locked in the first SELECT. I thought that locks were in place for the whole transaction, and so I wasn't expecting the query to return repeated results. Why is this happening?

servlet authentication and further reference to the credentials

- by user553592

What I got so far: It all begins with an HTML form which prompts the user for a username and password. From there it post the acquired user/pass to a servlet, GateKeeper. GateKeeper determines if the user/pass combination match any records in the MySQL database. Here is the sql I use: SELECT id FROM Users WHERE username='?' AND password=MD5('?') where the ? indicate information provided the previous HTML form. What I need now: I need some way to store the username and id of the record in the database. GateKeeper redirects the user to a control panel upon success. Therefore, I need a method to reference the username to display simple greetings, etc and also the id so it eliminates unnecessary calls to the database. The control panel may make AJAX calls to Servlets that preform some sort of task to the MySQL database.

Why isn't this button firing the anchor tag?

- by Noor

My idea is to press a button that takes me to a web page. I've created a thing that dynamically creates a button and an anchor tag. When the button is clicked, I want it to "click"/fire up the anchor tag.. I've uploaded a demo to my site, when you try it out just leave everything as it is. Click the first button then the add button right away.. then try to click the dynamically created button. Nothing happens, but if you watch the source you can find an anchor tag with the ID FL1000, I've set it up so that the anchor tag gets the ID from the value of the created button + 1000 just incase I need to use that ID.. Thanks guys... edit: this is optimized for google chrome, haven't tried it out with other browser.

How can I find if an arbitrary process is running under wow64?

- by LCC

I need a tool which will discover whether an arbitrary process is running in x86 or x64 mode on a machine. I need to do this programatically from C++, based on a process ID. There has to be some way to do this (as you can clearly see it from the task manager). Does anyone know of a windows api that will tell you, given a process ID, whether the application is running under wow64? Another approach would be to figure out, based on the process id, the executable name/path that is running and try to read the PE headers out of the file. Does anyone have a code snippet that would accomplish that?

elegant way to extract values from array

Something that bugs me for a long time: I want to convert this Array: // $article['Tags'] array(3) { [0] => array(2) { ["id"] => string(4) "1" ["tag"] => string(5) "tag1" }, [1] => array(2) { ["id"] => string(4) "2" ["tag"] => string(5) "tag2" }, [2] => array(2) { ["id"] => string(4) "3" ["tag"] => string(5) "tag3" }, } To this form: // $extractedTags[] array(3) { [0] => string(4) "tag1", [1] => string(4) "tag2", [2] => string(4) "tag3", } currently i am using this code: $extractedTags = array(); foreach ($article['Tags'] as $tags) { $extractedTags[] = $tags['tag']; } Is there any more elegant way of doing this, maybe a php built-in function?

Create tables for a dictionary?

I'm making a dictionary database in SQLite and need some tips. My SQL is a bit rusty ;) Would you consider this good SQL? It's done with Java JDBC. This is for creating the tables. CREATE TABLE word ( id INTEGER, entry STRING, pos STRING ); CREATE TABLE translation ( word_id INTEGER REFERENCES word(id), entry STRING ); And when filling with data i give each word a number (id) and that words translations get the same number as word_id. What would be the best way of pulling out translations for a specific word?
